Mount Desert island/ Acadia national park is really gorgeous. If you said you wanted to go kayaking - I would have a ton of suggestions of where you should do that. Mount Desert does have some gorgeous hiking & some nice roads for biking.


if you have a bunch of camping gear with you already and want to go kayak camping, I'd say go to:

You can rent boats or hire an outfitter & that's on the deer island archipelago - so if you stay in the inner islands, it's only 1-2 miles between every island, and you can hike around. The inner islands are fairly protected from the weather.

There's 2 sets of photos of kayaking around maine in my picasaweb - just scroll down & hit see more photos after the first batch:
